People assume he is not bright, but in IQ testing, his verbal and nonverbal areas are in the normal range. Executive functioning and working
memory are low, so testers dont add the scores because they feel it misleads. Sometimes he is given second chances in testing because he will blurt an incorrect answer before thinking--but knows the right answer. I have noticed when he is on ritalin, there is an improvement with his interacting and he comes across clever.
